What it is
Aleppo pepper, also called Halaby pepper, is a moderately hot variety of Capsicum annuum used mainly in Turkish, Middle Eastern and Mediterranean cooking. [1] It is named for Aleppo, an old Silk Road city in northern Syria, and is grown in Syria and Turkey. [1] The fruit is the part used. [1] In Turkish the flakes are called pul biber; "pul biber" in general means crushed chili, and a separate, specially prepared version is urfa pul biber, also called isot. [1][3]Flavor and aroma
Aleppo pepper is mild for a chili. One source puts it at about 10,000 Scoville heat units, a moderate level, with heat that builds slowly. [1] For comparison, another source lists a jalapeno at 3,500 to 10,000 and cayenne at 30,000 to 50,000. [2] The flavor is fruity and a little like raisins, with faint cumin-like notes. It is oilier and slightly salty. [1] One source compares its flavor to ancho chile. [1] The sources we read do not name the aroma compounds.How it is used in cooking
Aleppo pepper is mostly sold as crushed flakes, not fine powder. [1] It is a common ingredient in some meze dishes, and in Turkey pul biber is the third most used spice after salt and black pepper. [1] Crushed red chili in general is a table condiment and goes into soups, sauces and sausage. [3]- Heat level: because it is milder than most crushed red pepper, it works as a flavor spice, not only a heat spice. [1]
- Substitutes: one source names crushed red pepper or paprika as stand-ins. [1] Since plain crushed red pepper is hotter, use less and taste first. [1][3]
The sources we read do not say when to add it or whether to toast it, so we give no rules here.
Normal food amounts
| Measure | Grams | Source |
|---|---|---|
| 1 teaspoon, Aleppo pepper | Not listed | USDA has no entry [10] |
| 1 tablespoon, Aleppo pepper | Not listed | USDA has no entry [10] |
| Typical recipe amount | Not found | We opened no source that states one |
USDA SR Legacy has no entry for Aleppo pepper, so we give no nutrient numbers for it. Different chili products in the same file vary a lot (for example, a teaspoon of ground cayenne is 1.8 g and of paprika 2.3 g), so we do not guess. [10] A pinch of flakes is mostly flavor and heat.
Buying, storing and preparing
- How it is made: the pods ripen to a deep red, are partly dried, de-seeded and crushed or coarsely ground. Salt is often used during drying. [1]
- Names and look-alikes: Halaby and Aleppo are the same pepper. [1] Substitute products sold as "Aleppo-style" may be other chilies; the sources we read do not describe this, so check the label.
- Dyes: some traders have illegally added harmful synthetic dyes to chili products in general. [2] We found no source saying this has happened with Aleppo pepper.
- Shelf life: crushed red pepper in general loses heat over time and typically lasts 12 to 18 months. [3] This is a general figure for crushed chili, not Aleppo pepper itself.
Health: what research says
Eating Aleppo pepper as a spice on food is very different from taking concentrated chili capsules or using capsaicin products. We found no study of Aleppo pepper itself; the studies below are about chili in general.Food amounts vs supplements
| In normal cooking | In supplements and extracts | |
|---|---|---|
| Typical amount | A pinch to a teaspoon of flakes; no official amount found | Capsules and extracts are stronger than the cooking spice [4] |
| What studies mostly used | Questionnaires about how often people eat spicy food (chili pepper, sauce or oil), in large groups followed over years [5] | Capsaicin or capsinoids by mouth, and skin products [4] |
| What we can say about benefit | Observational links only; they do not show that chili causes a benefit [5][7] | Effects on appetite and calorie burning were small; a review found no effect on blood pressure or heart rate [4] |
| Main safety limit | Burning in the gut, skin and eyes; allergy [2][6][8] | Medicine interactions and pregnancy cautions [4] |
What the evidence shows
| Use | What the sources found | Strength of evidence | Form and population |
|---|---|---|---|
| Death from any cause or heart disease | A 2021 pooling of 4 cohort studies (564,748 adults, median 9.7 years) found 12% lower all-cause death and lower heart-disease death in regular spicy-food eaters, but no clear drop in stroke death. The authors asked for more studies. [5] | Mixed | Food (chili pepper, sauce, oil); adults, observational |
| Digestive-tract cancers | A 2022 pooling of 14 case-control studies found high chili intake linked to higher risk of digestive-tract cancers overall (odds ratio 1.64, interval 1.00 to 2.70) and of esophageal cancer (2.71), with no clear link for stomach or colon cancer. [7] | Mixed | Food; case-control studies, which cannot prove cause |
| Stomach symptoms | A 2010 review said a single chili dose can worsen pain and burning in dyspepsia and irritable bowel syndrome, while long-term chili intake improved dyspepsia and reflux symptoms in small randomized studies. [6] | Mixed | Food or capsaicin; small studies |
| Weight and blood pressure | MSK says effects on appetite and energy use were small, and a systematic review found no effect on blood pressure or heart rate. [4] | Insufficient evidence | Mostly capsaicin products, not cooking amounts |
| Any benefit from Aleppo pepper itself | No study found | Insufficient evidence | Food amounts |

Body systems (2)
- Digestive SystemPreliminary or mixed
Acute chili can worsen gut pain and burning in dyspepsia and IBS; long-term eating improved some symptoms in small studies.
- Heart & CirculationPreliminary or mixed
Observational pooling links regular spicy-food eating to lower heart-disease death; it cannot show chili is the cause.
Body parts (3)
- EyesDocumented risk
Chili oil irritates the eyes; keep hands away from the face after handling hot chilies.
- SkinDocumented risk
Capsaicin can irritate skin on contact, and washing does not remove it well.
- StomachDocumented risk
Chili can irritate the stomach and cause pain; MSK also reports stomach-lining injury in healthy volunteers who ate dietary capsicum.
Root causes (1)
- Medication Side EffectsDocumented risk
MSK describes possible interactions of cayenne supplements with blood pressure medicines, ACE inhibitors and cyclosporin; not stated for food.
Conditions & symptoms (5)
- DyspepsiaPreliminary or mixed
Acute chili can aggravate dyspepsia pain and burning; long-term chili intake improved symptoms in small randomized studies. Chili in general, not Aleppo specifically.
- Contact DermatitisDocumented risk
MSK cites a case of skin burn after handling red chili peppers.
- Food AllergyDocumented risk
Reviews describe spice allergy including pepper, from mild mouth reactions to anaphylaxis; MSK cites anaphylaxis to a chili pepper.
- HeartburnPreliminary or mixed
Long-term chili ingestion was reported to improve reflux symptoms in small randomized studies; a single dose differs.
- Irritable Bowel SyndromePreliminary or mixed
Acute chili can aggravate abdominal pain and burning in IBS.
Documented risks and interactions (5)
- Burning and skin or eye injury. Capsaicin causes the burning feel; it irritates skin and eyes and washing does not remove it well. Very hot peppers can cause stomach pain, sweating and vomiting.
- Medicine interactions (supplement level). MSK says capsaicin may change blood pressure medicines, may add to ACE-inhibitor cough, and should be avoided with cyclosporin after transplant; animal data suggest other interactions of unknown meaning.
- Pregnancy and breastfeeding. MSK says cayenne should be avoided in pregnancy and breastfeeding and cites skin irritation in nursing infants after mothers ate red-pepper-flavored food.
- Allergy and gut irritation. Reviews list pepper among spices that can cause allergy, from mild mouth reactions to anaphylaxis, with pollen cross-reactions; MSK cites anaphylaxis to a chili pepper.
- Illegal dyes in some chili products. Some traders have added harmful synthetic dyes to chili products in general.

Safety note at a glance
Safety in more detail
- Medicines: MSK says capsaicin may change the effect of blood pressure medicines, may add to the cough caused by ACE inhibitors, and should be avoided with cyclosporin after a transplant. Animal data point to other possible interactions; their meaning in people is unknown. [4] These points are for cayenne supplements; the sources we read do not state them for chili flakes in food.
- Pregnancy: MSK says cayenne should be avoided in pregnancy. [4] The sources we read give no limit for chili in cooking, so ask your midwife or doctor.
- Breastfeeding: MSK says to avoid cayenne while breastfeeding and cites cases of skin irritation in nursing infants whose mothers ate red-pepper-flavored food. [4]
- Children: the sources we read do not give a limit for chili in children's food.
- Allergy: reviews list pepper among spices that can cause allergy, from mild mouth reactions to anaphylaxis, with cross-reactions to pollen. The abstracts do not say whether "pepper" means chili or black pepper. [8][9] MSK cites a case of anaphylaxis to a chili pepper and a case of skin burn after handling red chilies. [4]
- Liver and kidney: the sources we read do not describe liver or kidney problems from chili in food.
- Surgery: the sources we read do not describe a surgery warning. Tell the surgical team about any supplement.
- Quality and contamination: illegal dyes have been found in some chili products. [2] Salt is often used in making Aleppo pepper, so check the label if you limit salt. [1]
- Amounts that cause trouble: hot peppers can cause stomach pain, sweating, hyperventilation and vomiting. [2] MSK lists eye or nose irritation and stomach irritation, and case reports of high blood pressure after large amounts of chili. [4] Aleppo pepper is milder than cayenne, but the sources do not give a safe amount.
